What are multi-stage rockets?

A multi-stage rocket is like a toy car that changes its wheels as it goes faster and farther.

Imagine you're playing with a race car. At first, it uses big, strong wheels to get moving. But once it’s going fast, those wheels are too heavy and slow. So the car swaps them for lighter, faster wheels. That helps the car zoom even faster!

A multi-stage rocket works in much the same way. It has different parts called stages, like the wheels of the toy car. Each stage is like a powerful engine that helps the rocket climb into space.

When the rocket starts, all the stages work together to lift it up. But once one stage finishes its job, it drops off, kind of like taking off your heavy boots when you're running fast. This makes the rocket lighter and faster, so it can go higher and farther!

Each time a stage drops off, the next one takes over. It’s like having new wheels for the rocket to keep going stronger and quicker!
